IMPROVEMENT IN STEAM-GENERATORS.

Specification forming part of Letters Patent No. 58,604, dated Octoberl 9, 1866.

To all whom it may concern:

Be it known that I, WM. GoNANT,of Geneva, in the county of Kane and State of Illinois, have invented a new and useful Improvement in Steam-Generators, and I do hereby declare the following to be a full, clear, and exact description of the nature, construction, and operation of the same, reference being had to the accompanying drawings, which are made a part ot' this specification, and in which- Figure l is a horizontal section of a steam generating and superheating apparatus illustrating my invention. Fig. 2 is a vertical section of the same.

Similar letters of reference indicate corresponding parts in the different gures.

The nature of my invention consists in an arrangement of apparatus for making super# hea-ted steam from water, which is first couverted into steam within a heated pipe or other contracted conductor, (one or more,) and then transferred to a more spacious receptacle, which I shall term a receiver,77 in which the steam is superheated to any desired degree.

The invention further consists in the nonconducting lining or casing which surrounds the tire-box and receiver, and serves to prevent the loss of heat by radiation.

In order that others skilled in the art to which my invention appertains may be enabled to fully understand and use the same, I will proceed to describe its construction and operation in detail, in connection with the accompanyin g drawings. y

A represents a pipe, which may have a coiled or other desired form, and be fixed within the fire-box B, or otherwise located, so as to be heated to the requisite extent to convert water into steam while passing through it. This pipe is connected with a water reservoir or tank, and water may be forced through it by a pump or any other means commonly employed for such purposes. The steam which is thus formed within the pipe A is discharged therefrom into a receiver, C, in which the steam is snperheated to any desired degrec, and from which it is drawn oft' for use.

The receiver G may be located within the iiue through which the heat and products of combustion escape from the tire-box B, and it may be heated in this way or by a separate lire, and its location relatively to the pipe A may be varied as desired.

I will here state that the number, arrangement, size, or shape of one or all of the above parts may be varied to suit the taste, and the invention can be carried out under many modified forms of apparatus.

It should be understood that in this generator it is not essential that the receiver be heated to a greater degree than the pipe in which the steam is formed, inasmuch as the superheating of the steam is effected by the continued or prolonged action of the heat upon it after it leaves the pipe A, in which latter it is only necessary for the water to re; main long` enough to be vaporized or changed into steam of comparatively low temperature.

The amount of water contained within the pipe A may be determined by the length or diameter of the latter, or the passage of the water through the saine may be regulated in any suitable way in order that the amount shall be made to conform to the heating capacity.

Into the receiver I propose to insert a blown pipe with stop-cock, for the purpose of blowing out any accidental accumulation of water in the receiver; also a conducting-pipe, for transferring the steam from the receiver t0 the point where it may be applied as a motive power; also a safety-valve, steam-gage, and any other appliances which may bedesirable.

One of the prime advantages resulting from this method of making and superheating steam is due to the fact that only a small or limited quantity of water is subjected to the action of the heat at once, which obviates eX- plosions, which frequently occur in consequence of the sudden transformation of large bodies of water into steam. A

This method is economical with respect to fuel, as the steam is taken off to be used as fast as it becomes superheated, and thus does not, as in ordinary generators, stand long under the action of the heat to preserve it intact.

The apparatus is light, durable, simple, and cheap in construction, and is adapted for effective use in many land and water conveyances, where its more weighty predecessors would not bc available.

I surround the receiver and the fire-box, if

desired, with zi lining or wall, D, of non-eon- 2.
